发明名称 Exposure method and apparatus
摘要 An exposure method illuminates a mask that forms a desired pattern and an auxiliary pattern smaller than the desired pattern, and projects light from the mask onto an object to be exposed via a projection optical system at a position offset from a focus position that provides the highest resolution so that the auxiliary pattern is not resolved.
